Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642606, here are decompositions:

73 + 8642533 = 8642606
97 + 8642509 = 8642606
139 + 8642467 = 8642606
157 + 8642449 = 8642606
223 + 8642383 = 8642606
277 + 8642329 = 8642606
409 + 8642197 = 8642606
433 + 8642173 = 8642606

Showing the first eight; more decompositions exist.
